Letters Patent No. 89,533, dated April 27,1869.

nvnmovnmmv'r m com-Hosanna The Schedule refen-ed to in these LettersPatent and making part of the same- To all whom it may concern.-

Be it known that I, ALONZO WHITGOMB, of Worcester, in the county ofWorcester, and State of Massa chusetts, have invented certain new anduseful Improve ments in Oorn-Husking Machines; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being hadto the accompanying drawings, making part of thisspecification, and to the letters of reference marked thereon, likeletters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

lgty invention relates'to machines for husking corn; an

The invention consists in a novel construction and arrangement of thevarious parts of the machine, as hereinafter explained.

Figure 1 is a vertical section on the line :v-x of fig. 2.

Figure 2 is a front elevation of the machine.

In constructing my machine, I construct a metal frame, A, of suitableform to constitute the bed and furnish bearings for the various shaftsand rollers.

In the lower part of this frame, I mount two parallel ro ls, coveredwith an elastic coating of rubber, similar to those used inclothes-wringers, with their surfaces more or less roughened, to insuretheir taking hold on the husks.

At one end these rolls are provided with pinions O, which gear into eachother, whereby the rolls are caused to revolve in the directionsindicated by the arrows marked thereon in fig. 1.

At one side of the frame A is mounted a drivingshaft, I, on which is aspur-wheel, F, which gears into the pinion O, on the adjoining roll J,and on this same shaft I is also secured a crank, K, for operating themachine.

On the opposite end of this shaft I is secured apinion, a, which gearsinto a gear-wheel, D, mounted on a. shaft, B, located transversely atthe top of the frame A, this shaft B also having secured to it a set ofradial wings, G, as shown more clearly in fig. 1, these wings beingarranged so that their outer edges shall pass alongjust over the rolls Hand J, as represented in fi -1.

A? the front side of the machine I secure a concave plate, I, asrepresented in the drawing, the lower edge of this plate P extendingover and nearly covering the roll H, as shown in fig. 1, thus formingboth a hopper for receiving the ear of corn, and also a guard, or shieldfor the roll H;

A balance-wheel, L, is secured upon the shaft of one or the other of thestripping-rolls, H or J, in this case it being attached to the roll J.

The roll H is mounted in adjustable bearings, which are set up byset-screws e, when necessary to bring the stripping rolls into properposition in relation to each other, and thereby insuring their seizinghold of the husks.

The concave 1? may be made adjustable, either with or independently ofthe adjustable roll.

By having the lower portion of the concave extend over the roll H, asrepresented, it follows that the ear of corn, instead of resting uponthis roll, rests partially upon the plate and partially on the roll J,and as the latter is revolving rapidly, the ear is caused to revolve orroll over also; whereas, if the ear rested equally on both rolls, itwould not'revolve at all, or but slightly, as the action of the tworolls upon it would simply counteract each other.

The car being dropped upon the concave, is moved gradually over therolls, until it comes in contact with roll J, when it is caused torevolve, and the husks are caught between the two stripping-rolls, andas the ear continues to revolve, the husks are all removed, the husksbeing thrown out below the rolls, and the car being thrown out at theopposite side by the wing O, as it sweeps along.

By this means I am enabled to construct a ver simple and eificientmachine.

Having thus described my invention,

What I claim, is.

'1. The rubbe'r-covered-rolls H and J, arranged in the same horizontalplane,'or nearly so, with a balance-wheel applied to the shaft of one ofthem, and both having motion imparted to them, for the purpose ofstripping the husks from cars of corn, substantially as .described.

2. In combination with said stripping-rolls, the concave 1?, arrangedsubstantially as set forth.

3. The combination of the rolls H J, the revolving wings C, and concaveP, when arranged substantially as described.

4. The use, in a corn-husking machine, of a concave, P,'so constructedand arranged as to cover one of the stripping-rolls, and keep the earfrom resting upon said roll while being husked, substantially asdescribed,
